maven - 如何在不使用进程调用的情况下从插件中以编程方式调用 Maven？

Question

我想从插件中调用 Maven 目标，并且不愿意接受将进程分叉作为初始化的成本。有没有办法做到这一点？

Answer 1

我怀疑这是一种受支持的方法，但它对我有用。

/**
 * @parameter expression="${session}"
 * @required
 * @readonly
 */
 private MavenSession session;

/**
 * @component
 * @readonly
 */
 private Maven maven;
/**
 * @parameter default-value="${project.remoteArtifactRepositories}"
 * @readonly
 **/
protected List<ArtifactRepository> remoteArtifactRepositories;
/**
 * The project's remote repositories to use for the resolution of plugins
 * and their dependencies.
 * 
 * @parameter default-value="${project.pluginArtifactRepositories}"
 * @readonly
 */
private List<ArtifactRepository> pluginArtifactRepositories;
/**
 * @parameter default-value="${localRepository}"
 * @readonly
 * */
private ArtifactRepository localRepository;

...

List<String> goals = ...
File pomFile = ...
MavenExecutionRequest req = new DefaultMavenExecutionRequest();
req.setPom(pomFile);
req.setBaseDirectory(pomFile.getParentFile());
req.setGoals(goals);
req.setProxies(session.getSettings().getProxies());
req.setMirrors(session.getSettings().getMirrors());
req.setLocalRepository(localRepository);
req.setRemoteRepositories(remoteArtifactRepositories);
req.setPluginArtifactRepositories(pluginArtifactRepositories);
MavenExecutionResult result = session.execute(req);

要内省处理，您可以继承 AbstractExecutionListener 并使用 req.setExecutionListener() 来应用它。
